Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567632, here are decompositions:

11 + 31567621 = 31567632
13 + 31567619 = 31567632
29 + 31567603 = 31567632
73 + 31567559 = 31567632
79 + 31567553 = 31567632
181 + 31567451 = 31567632
263 + 31567369 = 31567632
353 + 31567279 = 31567632

Showing the first eight; more decompositions exist.
